It has been reported by silvergoldsilver that he is hearing of a margin hike today. If this is true, then the Comex is trying to detect how many of the 60,000 plus March contract will be standing for drlivery in 7 trading days. If more than 10,000 contracts remain on the first day notice of delivery, then I am certain that silver will trade north of $40 within two days of that event.

For now, the Comex will raise the marigin requirement to see how many of those contract holders have the intention of standing for delivery because at this point in time, if you do not have any intention of standing for delivery then you would sell the March contracts ratther than ante up more money on a position that you were going to roll out in a few more days.
